Land Rover Discovery TD5 brain box problem

[Nawao]

Hi all:

My name is Alex, I leave & work in Nigeria for a landscaping company. I purchased a 2003 Land Rover Discovery TD5 manual gear from a friend. The vehicle is almost new with just 15000 km but has not been in use for the past 6 months because of brain box problem. I contacted the Land Rover representative in Nigeria and their policy is to charge a registration fee of USD 4000 to any vehicle not purchased from them and another USD 4000 for tropicalisation. After that they will agree to quote for the repair of the actual problem… Is this the standard requirements for service? It seems a brain box must be installed in the vehicle in order to be reprogrammed… To purchase the diagnostic tools for troubleshooting electronic problems and to reprogram the brain box is not feasible for me, so I’m unclear what to do. With my experience for this country is better to use a vehicle with a simple engine management, that is far to be the case with the TD5… To much electronic! Then when you have a problem you have to give your skin to expensive organisations that are not really conversant with this type of technology. The questions are:
1) What kind of modifications are possible to do enabling that engine to run without so much electronics, when I say modifications means, keeping the engine block but changing the injection system with a normal injection pump and injectors, cylinder heads, and whatever else needed to make this vehicle less complicated…
2) What kind of simple Land Rover turbo diesel engine can replace the TD5 in my Discovery?

Hope to get soon reply to help me solve this issue!

Regards to all.

Alex.
